我们能解释一下这段代码吗，我不明白它是如何工作的.....

jQuery....jquery.pstrength-min.1.2.js file.... password strength

can we plz explain this code i can''t understand how it is working.....

(function(A) {
    A.extend(A.fn, { pstrength: function(B) {
        var B = A.extend({ verdects: ["Very weak", "Weak", "Medium", "Strong", "Very strong"], colors: ["#f00", "#c06", "#f60", "#3c0", "#3f0"], scores: [10, 15, 30, 40], common: ["password", "sex", "god", "123456", "123", "liverpool", "letmein", "qwerty", "monkey", "111111111", "22222222", "333333333", "44444444"], minchar: 6 }, B);
        return this.each(function() { var C = A(this).attr("id"); A(this).after("<div class=\"pstrength-minchar\" id=\"" + C + "_minchar\">Minimum number of characters is " + B.minchar + "</div>"); A(this).after("<div class=\"pstrength-info\" id=\"" + C + "_text\"></div>"); A(this).after("<div class=\"pstrength-bar\" id=\"" + C + "_bar\" style=\"border: 1px solid white; font-size: 1px; height: 5px; width: 0px;\"></div>"); A(this).keyup(function() { A.fn.runPassword(A(this).val(), C, B) }) })
    }, runPassword: function(D, F, C) { nPerc = A.fn.checkPassword(D, C); var B = "#" + F + "_bar"; var E = "#" + F + "_text"; if (nPerc == -200) { strColor = "#f00"; strText = "Unsafe password word!"; A(B).css({ width: "0%" }) } else { if (nPerc < 0 && nPerc > -199) { strColor = "#008080"; strText = "Too short"; A(B).css({ width: "5%" }) } else { if (nPerc <= C.scores[0]) { strColor = C.colors[0]; strText = C.verdects[0]; A(B).css({ width: "10%" }) } else { if (nPerc > C.scores[0] && nPerc <= C.scores[1]) { strColor = C.colors[1]; strText = C.verdects[1]; A(B).css({ width: "16%" }) } else { if (nPerc > C.scores[1] && nPerc <= C.scores[2]) { strColor = C.colors[2]; strText = C.verdects[2]; A(B).css({ width: "18%" }) } else { if (nPerc > C.scores[2] && nPerc <= C.scores[3]) { strColor = C.colors[3]; strText = C.verdects[3]; A(B).css({ width: "20%" }) } else { strColor = C.colors[4]; strText = C.verdects[4]; A(B).css({ width: "22%" }) } } } } } } A(B).css({ backgroundColor: strColor }); A(E).html("<span style='color: " + strColor + ";'>" + strText + "</span>") }, checkPassword: function(C, B) { var F = 0; var E = B.verdects[0]; if (C.length < B.minchar) { F = (F - 100) } else { if (C.length >= B.minchar && C.length <= (B.minchar + 2)) { F = (F + 6) } else { if (C.length >= (B.minchar + 3) && C.length <= (B.minchar + 4)) { F = (F + 12) } else { if (C.length >= (B.minchar + 5)) { F = (F + 18) } } } } if (C.match(/[a-z]/)) { F = (F + 1) } if (C.match(/[A-Z]/)) { F = (F + 5) } if (C.match(/\d+/)) { F = (F + 5) } if (C.match(/(.*[0-9].*[0-9].*[0-9])/)) { F = (F + 7) } if (C.match(/.[!,@,#,$,%,^,&,*,?,_,~]/)) { F = (F + 5) } if (C.match(/(.*[!,@,#,$,%,^,&,*,?,_,~].*[!,@,#,$,%,^,&,*,?,_,~])/)) { F = (F + 7) } if (C.match(/([a-z].*[A-Z])|([A-Z].*[a-z])/)) { F = (F + 2) } if (C.match(/([a-zA-Z])/) && C.match(/([0-9])/)) { F = (F + 3) } if (C.match(/([a-zA-Z0-9].*[!,@,#,$,%,^,&,*,?,_,~])|([!,@,#,$,%,^,&,*,?,_,~].*[a-zA-Z0-9])/)) { F = (F + 3) } for (var D = 0; D < B.common.length; D++) { if (C.toLowerCase() == B.common[D]) { F = -200 } } return F }
